Measurement of the $B^0_\mathrm{s}\to J/\psi K^0_\mathrm{S}$ effective lifetime from proton-proton collisions at $\sqrt{s} = 13$ TeV / CMS Collaboration
The effective lifetime of the $ \mathrm{B}_{s}^{0} $ meson in the decay $ \mathrm{B}_{s}^{0} \to \mathrm{J}/\psi\mathrm{K^0_S} $ is measured using data collected during 2016-2018 with the CMS detector in $ \sqrt{s}= $ 13 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 140 fb$ ^{-1} $. The effective lifetime is determined by performing a two-dimensional unbinned maximum likelihood fit to the $ \mathrm{B}_{s}^{0} $ meson invariant mass and proper decay time distributions. [...]

Measurement of the $ {\mathrm{t}\overline{\mathrm{t}}} \mathrm{H} $ and $ \mathrm{t}\mathrm{H} $ production rates in the $ \mathrm{H}\to\mathrm{b}\overline{\mathrm{b}} $ decay channel using proton-proton collision data at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
An analysis of the production of a Higgs boson (H) in association with a top quark-antiquark pair ($ {\mathrm{t}\overline{\mathrm{t}}} \mathrm{H} $) or a single top quark ($ \mathrm{t}\mathrm{H} $) is presented. The Higgs boson decay into a bottom quark-antiquark pair ($ \mathrm{H}\to\mathrm{b}\overline{\mathrm{b}} $) is targeted, and three different final states of the top quark decays are considered, defined by the number of leptons (electrons or muons) in the event.

Search for long-lived heavy neutral leptons in proton-proton collision events with a lepton-jet pair associated with a secondary vertex at $ \sqrt{s} $ = 13 TeV / CMS Collaboration
A search for long-lived heavy neutral leptons (HNLs) using proton-proton collision data corresponding to an integrated luminosity of 138 fb$ ^{-1} $ collected at $ \sqrt{s} = $ 13 TeV with the CMS detector at the CERN LHC is presented. Events are selected with a charged lepton originating from the primary vertex associated with the proton-proton interaction, as well as a second charged lepton and a hadronic jet associated with a secondary vertex that corresponds to the semileptonic decay of a long-lived HNL.

Measurement of boosted Higgs bosons produced via vector boson fusion or gluon fusion in the $ \mathrm{H}\to\mathrm{b}\overline{\mathrm{b}} $ decay mode using LHC proton-proton collision data at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A measurement is performed of Higgs bosons produced with high transverse momentum ($ p_{\mathrm{T}} $) via vector boson or gluon fusion in proton-proton collisions. The result is based on a data set with a center-of-mass energy of 13 TeV collected in 2016-2018 with the CMS detector at the LHC and corresponds to an integrated luminosity of 138 fb$ ^{-1} $. [...]

Measurement of the fractional radiation length of a pixel module for the CMS Phase-2 upgrade via the multiple scattering of positrons / Tracker Group of the CMS Collaboration
High-luminosity particle collider experiments such as the ones planned at the High-Luminosity Large Hadron Collider require ever-greater vertexing precision of the tracking detectors, necessitating also reductions in the material budget of the detectors. Traditionally, the fractional radiation length ($x/X_0$) of detectors is either estimated using known properties of the constituent materials, or measured in dedicated runs of the final detector.

Nuclear medium effects on $ {\mathrm{B}^{+}} $ meson production are studied using the binary-collision scaled cross section ratio between events of different multiplicities from proton-lead collisions. Data, collected by the CMS experiment in 2016 at a nucleon-nucleon center-of-mass energy of $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 8.16 TeV, corresponding to an integrated luminosity of 175 nb$^{-1}$, were used.

Observation of double $ \mathrm{J}/\psi $ meson production in pPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} $ = 8.16 TeV / CMS Collaboration
The first observation of the concurrent production of two $ \mathrm{J}/\psi $ mesons in proton-nucleus collisions is presented. The analysis is based on a proton-lead (pPb) data sample recorded at a nucleon-nucleon center-of-mass energy of 8.16 TeV by the CMS experiment at the CERN LHC and corresponding to an integrated luminosity of 174.6 nb$^{-1}$.

Measurement of the polarizations of prompt and non-prompt $ \mathrm{J}/\psi $ and $\psi \text{(2S)} $ mesons produced in pp collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
The polarizations of prompt and non-prompt $ \mathrm{J}/\psi $ and $\psi \text{(2S)} $ mesons are measured in proton-proton collisions at $ \sqrt{s} = $ 13 TeV, using data samples collected by the CMS experiment in 2017 and 2018, corresponding to a total integrated luminosity of 103.3 fb$ ^{-1} $. Based on the analysis of the dimuon decay angular distributions in the helicity frame, the polar anisotropy, $ \lambda_\vartheta $, is measured as a function of the transverse momentum, $ p_{\mathrm{T}} $, of the charmonium states, in the 25-120 and 20-100 GeV ranges for the $ \mathrm{J}/\psi $ and $\psi \text{(2S)} $, respectively.
